The IDS Center in Minneapolis was designed by Philip Johnson with Johnson/Burgee Architects and Edward F. Baker Associates for Investors Diversified Services, now Ameriprise, as its headquarters. The infobox gives a 1969 start and 1973 completion. The text gives only 1973 but says it became the city's tallest building in 1972. Construction cost 13.5 million dollars.
Johnson's stepback design, which he called zogs, gives each floor up to 32 corner offices. Glass is the only material named. The roof is 792 feet (241 m) and the spire 910 feet, which the page also lists as 280 m. It has 57 floors, 52 of them occupied. The article names no style.
Dayton Hudson Corporation was headquartered there from 1972 to 2001. The 51st-floor observation deck closed in 1984. Owners since IDS have included Oxford Development, John Buck, Inland and Beacon. The article gives no visitor access or hours.
